The Quickest way to do this is to turn Difficulty to expert, driving style to simulation and go to solo mode. Choose custom championship, and create a new one. Choose a WRC car and select any rally from any country, ( I did China as it only has 1 stage per day). Start the 1st stage and crash into things, not too heavy at first as you will need to damage the car all over so you have options of what to repair. Once your car is at least orange all over have a big head on crash with a rock or barricade & your engine will go red. Press start, select give up and it will take you back to the paddock. Select repair, then tinker between different parts of the car until your total repair time is 45’ of 45’. Select accept & the achievement will pop.
